ABSTRACT

【Objective】 To evaluate the associations of total fat and fatty acid consumption with the risk of hypertension among rural residents in Hanzhong, Shaanxi Province. 【Methods】 A cross-sectional survey on dietary status with a semi-quantitative food frequency questionnaire was conducted among rural residents aged between 18 and 80 years old in Hanzhong of Shaanxi. Multivariate log-binomial regression models and restricted cubic spline were used to explore the associations of dietary total fat, saturated fatty acid, polyunsaturated fatty acid and monounsaturated fatty acids with hypertension and as well as association between dose and response. 【Results】 A total of 2241 individuals were included, with 774 males and 1467 females. Monounsaturated fatty acid accounted for 51.9% of total dietary fat intake, while the other two fatty acids for 48.1%. The intake of dietary fat and any fatty acid in men was significantly in men higher than in women (P<0.001). Results of multivariable log-binomial regression indicated that after adjustment of energy, socio-demographic and lifestyles, the risk of hypertension reduced significantly in Q4 group, compared with that in Q1 (PR: 0.71, 95% CI: 0.54-0.92; P-trend: 0.022) in females. A nonlinear dose-response relationship between monounsaturated fatty acids and hypertension was detected by restricted cubic spline in women (Pnon-linear<0.01). No association was observed of total fat, saturated fatty acid and polyunsaturated fatty acid with hypertension regardless of the gender. 【Conclusion】 In women, increased consumption of monounsaturated fats might play a positive role in reducing the risk of hypertension. Further research is warranted to verify the rationality of causal inference and break-point.

ABSTRACT

Objective To reveal the role of serum ACE2/Ang (1-7)in the occurrence of atrial fibrillation (AF)and find new targets for the prevention and treatment of AF by analyzing the correlation between the serum concentration of ACE2/Ang (1-7 )in patients with rheumatic valvular heart disease and the occurrence of AF. Methods We collected the basic clinical information and peripheral venous blood of patients with rheumatic heart valve disease (totally 46 patients,including 24 with AF and 22 with SR).ELISA method was used to detect the serum concentration of ACE2,Ang (1-7)and AngⅡ in the serum samples.Then the differences and correlation between the two groups were analyzed.Results In the AF group ① the diameter of the left atrium was significantly greater than that in the SR group [(60.70±3.08 vs.48.15±2.16)mm,P<0.05];② the serum concentration of AngⅡ was significantly higher than that in the SR group [(45.88±2.87 vs.35.78±1.08)pg/mL, P<0.05],AngⅡ and left atrium diameter were positively correlated (Pearson test,P<0.05);③ the serum concentrations of ACE2 [(7.87±0.74 vs.11.65±0.57)U/L,P<0.05]and Ang (1-7)[(146.05±17.61 vs. 321.71±36.50)pg/mL,P<0.05]were significantly lower than those in the SR group,and negatively correlated with left atrium diameter (Pearson test,P<0.05);④ the serum concentration of Ang (1-7)was negatively correlated with AngⅡ concentration (Pearson test,P<0.05).Conclusion For patients with rheumatic valvular heart disease,ACE2/Ang (1-7 )may play a protective role in the occurrence of AF via antagonizing AngⅡ and inhibiting atrial remodeling.

ABSTRACT

Objective To study the current status and risk factors of spontaneous abortion of women with Tibetan ethnicity at reproductive age in rural areas.Methods Pregnant women who lived in fibet were interviewed on their former reproductive history and being followed on the outcomes of pregnant from 2006 to 2012.Generalized Poisson regression model was used to explore the influencing factors of spontaneous abortion.OR value of the research factors was estimated and its 95% confidence interval counted.Results There were 1 557 pregnant women under this study,with a total number of 2 687 pregnancies and 2 382 productions.171 women underwent spontaneous abortion,with a total number of 204 times,93 women had histories of abortion,with a total number of 101 times.Among all the Tibetan pregnant women,the ratio between spontaneous abortion and pregnant women was 7.6% while the rate of spontaneous abortion was 7.9%.Ratio between the number of women who had experienced spontaneous abortion and the total number of women under survey was 11.0%.Pregnancy appeared the important reason on spontaneous abortion.The risk of having spontaneous abortion would increase among women who had more than 3 pregnancies.Results from Poisson regression analysis revealed that the odds ratio (OR) value before the adjustment was 3.921 (95%CI:2.553-6.021) but after the adjustment,it increased to 4.722 (95%CI:2.834-7.866).The increase of production time could reduce the risk of spontaneous abortion in women of childbearing age.Risks related to spontaneous abortion were associated with the number of pregnancies.Women seemed to have lower risk for spontaneous abortion after 2009,with OR value as 0.419(95%CI:0.285-0.616) before,compared to aOR value as 0.580 (95%CI:0.380-0.885) after the adjustment Social-demographic characteristics was not found to be particularly associated with the occurrence of spontaneous abortion.Conclusion Rate of spontaneous abortion among Tibetan women at childbearing age was not particularly high when comparing to those women living in the plain area such as Shaanxi.However,in order to further reduce the incidence of spontaneous abortion among Tibetan women,approaches should include the following items:strengthening maternal health care,extending the spacing of pregnancy and reducing the frequency of pregnancy.

ABSTRACT

Objective To investigate the growth pattern of rural Tibetan children in the first year after birth.Methods In rural area of Lhasa,Tibet,252 subjects were recruited and their weight,length were measured longitudinally from birth to 12th months of age.Frequency of monitoring reached 5 times in total and Ponderal index (PI) was calculated for each visit.Mixed model was used to analyze the changes of length and weight by gender after controlling for birth weight.Results Birth weight and length showed great influence on children' s growth (weight:β =-0.681 9,P<0.000 1,length:β =-0.957 1,P<0.000 1).Weight and length of Tibetan male infants at each age point were lower than WHO new standard on growth and the Reference from 2005 National Survey on growth of children in China.The gap seemed widened by time but the gap between Tibetan female infants and Chinese standard narrowed 6 months after birth.Data showed that the higher PI of Tibetan infants than that of other Chinese infants which might infer that Tibetan infants had a more solid body mass under their own height.Conclusion The growth pattern of Tibetan infants might have its own feature.Tibetan infants appeared to have had higher PI,which was contradictory to the general conclusion that poor growth and development status had been seen in Tibetan children.
